METALLIC HAME.

SPECIFICATION forming part of Letters Patent No. 240,735,dated April 26,1881.

Application tiled November 11, 1880.

To all whom it may concern:

Be it known that I, EMMIT G. LATTA, of Friendship, in the county ofAllegany and State of New York, have invented new and usefulImprovements in Metallic Eames, of which the following is aspecification, reference being had to the accompanying drawings. TheObject of this `invention is to produce a cheap, light, and durablehaine which will Vfit the collar better than those now in common use,and in which the parts which are liable to become worn or broken can beeasily replaced, and the parts of which are readily molded, cast, andput together. My invention consists, first, of an open-bac metallic hameconstructed on its inner edge with a projecting ange which is adapted toiit under the rim of the collar, whereby a better tit of the hameagainst the collar is produced; second, of an open-back metallic hameconstructed on both its inner and-outer edges with projecting iianges,whereby tliestrengtli of the hame is increased anda better fit of thehame against the collar is" produced; third; of a metallic haineconstructed on its outer side with a slot for the reception of thedrafteye; fourth, of a metallic hame constructed on its outer side witha iiange having a slot formed in it for the reception ofthe draft-eye,the flange being re-enforced around the slot to a'ord a iirm bearing forthe shank of the draft-eye, fth, in combination with a hame providedwith a slot for the reception of the draft-eye, of a draft-eye having ashank engaging in said slot and adapted to be secured to the hamebyarivet or screw; sixth, of a metallic hame provided with sockets forthereception of the terret or rein-ring; seventh, of the particularconstruction of the sockets whereby they are enabled to be cast withoutcores; eighth, in the combination, with a metallic hame provided withsockets forthe reception of the terret or hamering, of a terret orhame-ring provided with a shank which is adapted to be introduced intothe sockets of the hame and secured therein by strengthening the shank;ninth, of a metallic open-back hame constructed with` a series ofprojections on its inner rear side. to receive an adjustable `5ohame-strap loop; tenth, in combination with` (No model.)

` strap loop in which the side bars are bent in opposite directions topermit the pattern to be drawn from the sand, and to facilitate theinsertion of the hame-strap. 6o

In the accompanying drawings, consisting ot' two sheets, Figure 1 is arear elevation, and

Fig. 2 a front elevation, of my improved hame.

` Fig. 3 is a fragmentary sectional elevation of `the upper part of thehame on an enlarged scale. Fig. 4 is a horizontal section in line l i l,Fig. Fig. 5 is a front elevation, on an enlarged scale, of that part ofthe hame to which the terret is attached. Fig. 6 is a rear elevation ofthe same. in line 2 2, Fig. 5. Fig. 8 is a detached view of the terretprevious to applying it to the hame. Fig. 9 is a `cross-section of thehame applied to the collar. Fig. 10 is .a cross-section ofthe hame,showin g a moditiedform thereL 7 5 of. Fig. 11 is a cross-section inline 3 3, Fig. 2, o1i` an enlarged sale. Fig. l2 is a vertical sectionin line 4.4, Fig. ll, on an enlarged scale. Fig. 13` is a detached viewof the draft-eye. Fig. 14 is a detached view of the lower hame- 8o straploop. Figs.15 and 16 showniodified constructions of the terret.

Like letters of reference refer to like parts lin the several figures. v

A represents the body of inyiinproved hame, 8 5 made of semicircular orsimilar cross-section, with an open or depressed back, and havinglaterally-projecting iianges a a on the inner and outer edges of thebody of the hame.

B represents the upper hame-strap loop, C` 9o the terret or rein-ring, Dthe draft-eye, and- E the lower hame-strap loop.

The llanges a a extend from the lower portion of the hame, where theyrun out into nothing, upward to apoint below the terret', where` 95 theyalso run out into nothing, and are widest near the draft-eye, as clearlyshown inFigs.

l and 2. The i-nner'flange, a, is adapted tot` under therim of thecollar, and both flanges are shaped to lit snugly against the collar,roo

Fig. 7 is a vertical section 7o` whereby the hame is given a firmbearing against the collar and a close fit of the parts is produced. Thehame has about the same thickness of metal throughout the entire lengthof its cross section, as clearly shown in Fig. 9, and the flanges a agreatly' increase the strength of the hame and permit the same to bemade light.

f represents several projections formed on the inner rear side of thehame, at the upper portion thereof, at suitable distance apart forholding the upper hame-strap loop, B, in the proper position. The loop Bis composed of' a narrow portion which surrounds the hame, and a widerportion through which the hame-strap is drawn.

g is a tongue or stop projecting inwardly from one of the side bars ofthe loop, and arranged in such manner that when the hamestrap isdisconnected from the loop the stop g will pass by the projections f ofthe hame and permit the loop to be freely raised and lowered. Uponpassing the hame-strap behind the inner bar ot' the loop the latter isdrawn inward, so as to bring the stop g between two of the projectionsf, whereby the loop is held against vertical movement. By this means theloop B is readily adjusted on the hame, and secured in the desiredposition without obstructing the outer surface of the hame bycorrugations, as heretofore practiced.

h h are two sockets, formed one above the other on the outer side of thehame for the reception of the shank of' the ter'ret C. The sockets 71.open toward each otherthat is, the upper socket opens downward and thelower socket upward. i

t represents an opening, formed in the rear side of each socket, h, andcommunicating with the recess of the socket, so that the pattern can bedrawn from the sand, thereby avoiding the use of cores.

lq represents the shank of the terret, which is provided with two arms,which are adapted to en gage in the recesses of the sockets h. One ofthe arms of' the shank lc, preferably the upper one, is made longerthanthe lower arm, and bent as shown in Fig. 8, and the upper socket, h,is made correspondingly longer, so that the upper bent end of the shankcan be passed into the upper socket far enough to drop the short lowerend into the lower socket. This being done, the Lipper bent arm of theshank is straightened out, as shown in Fig. 6, whereby the terret isfirmly attached to the hame.

Instead of constructing the terret C with a bent shank, which isstraightened after its ends are inserted in the sockets, the terretmaybe constructed of spring metal, as represented in Figs. 15 and 16,and sprung into the sockets.

. The draft-eye D is constructed with a fiat shank, L, which is passedthrough a vertical slot, Z, in the outer flange, a', of the hame, andwhich bears against the rear side of the body of the llame. The grooveor depression in the back of the body of the hame is filled up at thispoint, so as to form a bearing for the flange or shank L. The flange cis also re-enforced or made thicker around the slot Z, to afford a firmbearing for the shank of the draft-eye. m represents a rivet or screwwhereby the shank L of the draft-eye is secured to the hame. When theeye has become worn by use, it is readily detached by removing the rivetor screw m, and replaced by a new one. The shank L of the draft-eyerests in a depression formed in the outer flange, a', of the hame, andthe rivet is substantially relieved from all strain in pulling on thedraft-eye.

N is the eye or loop to which the holdbackring is attached. It ispreferably formed in one piece with the draft-eye, as shown, but it maybe formed at the outer end of the rivet m, by which the draft-eye issecured to the hame.

'Ihe lower hame-strap loop, E, has its side bars, o, bent or curved inopposite directions, one outward and one inward, as clearly shown,whereby the pattern is enabled to be drawn from the sand, and the use ofcores in casting the loop is avoided, and the shape of the loop renderedmore suitable for an easy attachment of the hame-strap, since the frontbars of the two loops are curved in opposite directions or away fromeach other and permit the fingers to en ter between the front bars, evenwhen the loops are brought closely together.

The parts of' my improved hame are each easily molded and cast completeof malleable iron, and readily put together.
